If you do a search for Chocolate Armenteros on that site you will find many of his best recordings.
Thru the same same site you could obtain Arsenio's recordings.. This was one of the first bands "Choco" played in professionaly. It featured a 3 man trumpet section and a style that is as "hip" today as it was in the mid-forties.
Chocolate Armenteros style is what made me fall in love with trumpet playing when I was 12 years old. As much as I listen to the greats of trumpet playing in all the genres of music I always end up listening to some Chocolate recording to this day. He just sings thru his horn in such a way that even non-musicians could identify him with just one or two notes out of his horn.
Ray did an excellent interview with him a couple of years ago when he was being honored at the New York Brass Conferance.....Perhaps copies of that Brass Conferance publication are still available?
